Property Value


The label for the message queue. The default is an empty string ("").



The label was set to an invalid value.

An error occurred when accessing a Message Queuing method.


The following code example gets and sets the value of a message queue's Label property.

// Set the queue's Label property value.
queue.Label = "Example Queue";

// Display the new value of the queue's Label property.
Console.WriteLine("MessageQueue.Label: {0}",


The maximum length of a message queue label is 124 characters.

The Label property does not need to be unique across all queues. However, if multiple queues share the same Label, you cannot use the Send(Object) method to broadcast a message to all of them. If you use the label syntax for the Path property when you send the message, an exception will be thrown if the Label is not unique.
